what is rifting?

Answer 1

rift

noun

1. A usually narrow partial opening caused by splitting and rupture: break, chink, cleavage, cleft, crack, crevice, fissure, split. See open/close.
2. An interruption in friendly relations: alienation, breach, break, disaffection, estrangement, fissure, rent2, rupture, schism, split. See assemble/disassemble, help/harm/harmless.

verb

To crack or split into two or more fragments by means of or as a result of force, a blow, or strain: break, fracture, rive, shatter, shiver2, smash, splinter, sunder.

Answer 2

Short answer: a place where the earths crust is "spreading", essentially tearing a crustal plate apart. Imagine taking a thick slab of clay and slowly pulling it apart. The middle of the clay slab gets thinner as it stretches out and if it were allowed too, it would sink a bit.. creating a valley.
Very much the same thing happens to a crustal plate as it is torn apart (african rift, rio grande rift etc.. are both valleys caused by rifting). It is more complicated than this, and has very special implications for processes occurring underneath the rift... but that is another long discussion

Answer 3

What Is Rifting

Answer 4

The Earth's surface is composed of chunks of continental and oceanic crust that float in top of the lower mantle material. These chunks are referred to as plates. Plate boundaries can be very complex or simple. Here in California the North American plate is sliding past the Pacific plate along the San Andreas fault. The other side of the North American plate is located in the middle of the Atlantic Ocean where oceanic crust is bubbling up from below and moving away from a long crack that lies in a north south line. That line is a rift...crust material forming and moving away from the center and pushing the plates around. Rifting also occurs in Eastern Africa. Rifting is also called spreading centers.

So where does it all go? Down subduction zones, like the one in the western Pacific ocean near Japan. In subduction plate boundaries, oceanic crustal material is pushed down, usually under continents. This decent of material is one of the sources of the earthquakes in Japan.

Or where two plates of continental material collide the rocks just keep pushing up. This is happening where the Indian subcontinent is colliding with Asia and pushing up the Himalaya Mountain range.

Answer 5

When the diverging plate boundary is present within the continent, it results in rifting. Example East African rift valley.

Answer 6

Rift. n. A long, narrow crack in the entire thickness of the Earth's crust, which is bounded by normal faults on either side.

Answer 7

In geology, a rift is a place where the Earth's crust and lithosphere are being pulled apart.

Yes we cant really say 100%, we can only speculate. The England series hurt the Indian team mentally and I feel that havnt got over it yet, which has snowballed. India should have done more damage to the WI at home and was close to losing the final Test, which didnt help the positive mental state they needed to bring to Australia. The raw heart of the Indian team, who i believe to be Harbhajan Singh was missed in Australia and the strongest mind in Dravid couldnt continue his English form. The truth is, India have lacked the persistence and fortitude to hold onto number 1 spot, whether it be mental or physical, they need to channge the current situation because its not working

Answer 9

the splitting apart of the earth's crust when it is stretched by tectonic activity. Results in the downfaulting of blocks of crust and creation of flat-floored valleys or troughs known as rift valleys (eg, Virginia's Triassic lowlands)

Answer 10

Hi. A geologic feature from breaking rock on a large scale.
